Urgent: Integrating Estimated Delivery Date and Delivery Timeslots on WooCommerce

I have an e-commerce site built using WooCommerce and I urgently need a WooCommerce and PHP expert to help with the integration of 2 paid plugins that I have purchase, to achieve the functionality required. Deadline: 11 April 2019 (GMT +8) I am currently using 2 paid plugins to display the following: 1. Estimated Delivery Date -- This estimated delivery date is being displayed on the individual product page as well as the checkout page to provide customers with a gauge on the estimated delivery time. I am currently using the "Estimated Delivery Date Plugin For WooCommerce" by PluginHive ([login to view URL]) which allows me to set different estimated dates for different products and product variations. - On top of this, they also have an add-on plugin that allows me to manage backorder products and set different estimated delivery dates for in-stock products vs products that are currently out of stock and requires backorder (a longer estimated delivery date will be displayed). 2. Delivery Time Slots -- I'm using the "Order Delivery Date Pro for WooCommerce" from Tyche Software ([login to view URL]) to allow customers to select their preferred delivery date and time slots. Depending on the time slots selected (e.g. Morning, Afternoon, Evening or Normal Working Days vs Public Holidays), they will be charged a different delivery date. -- Also, the preferred delivery date and time slot will be displayed on the customers' invoice and delivery slip as well as my backend WooCommerce Orders to allow me to schedule deliveries. However, as I am using 2 separate plugins, and there is no way for me to integrate the estimated delivery date to the delivery time slots at the check-out page. I need the dates to be integrated in such a way: - If the estimated delivery date for a product shows that it will be delivered between (1 May - 10 May), then the earliest selectable date of the preferred delivery date should be 1 May (all earlier dates are blocked out from the dropdown calendar). - If there are multiple products being purchased in an order, the earliest selectable date for the preferred delivery date should be the earliest estimated delivery date for the product with the latest estimated delivery date (i.e. in most cases, backordered products). - Bonus: If you are able to dynamically change the estimated delivery date at the individual product page based on the customers' input quantity (before clicking on the add to cart button), be it through dynamic AJAX calls or jQuery, I am willing to pay more. Kindly refer to the attached PDF for more information. This project is very urgent and I need it to be done latest by 11 April 2019 (GMT +8). Please only bid for it if you are 100% confident that you can achieve the required functionality. I am open to other proposed solutions if you have a better way of doing this, be it through the additional of code snippets or installation of a separate plugin. Kindly include your proposed solution in your bids so that I am able to understand your offer better. If you require any further clarifications, feel free to leave me a private message.
